A Williamsburg mother says her local playground is no longer safe after she and her 4-year-old daughter were attacked by teens pelting water balloons at them. Brynn Gingras reports. (Published Wednesday, June 13, 2012)

A Brooklyn mother is now staying away from Cooper Park in East Williamsburg, after she says her four-year-old daughter was pelted with water balloons by a group of teenagers.

The mother, who didn't want to be identified for fear of retaliation, tells NBC 4 New York she was playing with her daughter on the jungle gym Monday afternoon, when the teens fired a water balloon directly at her child.

"I saw her head go sideways, and she hit her lip on the bar," she said Wednesday. "I thought it was an accident."

But when the woman confronted the teens, she said the situation escalated.

"They started pelting me with balloons, and I was holding my baby," she said. "It felt like rocks."

Even as she tried to drive away, the woman claims the teens surrounded her car and threw balloons at her car as well.

Remnants of the balloons were still stuck to the car's exterior Wednesday.

Police are aware of the incident. A lieutenant has contacted the mother and promises to address the issue and maybe try to identify the suspects.
